ABSTRACT:
Process for the catalytic hydrogenation of a nitrite in the presence of an amine and a catalyst wherein the catalyst is a liquid-rinsed Raney-type catalyst contacted with a hydroxide prior to contacting the catalyst with the amine. The process results in higher selectivity in the formation of diamines from diniriles.
